Transparent shoe sole associated with internal gel with common shock absorbers ovals to cushion the impact when walking

ABSTRACT

The present invention refers to a clear shoesole, soft and flexible polyurethane that is complemented with a matching shoeplate gel that can be removed from the shoe. Both show the same design of oval-shock absorbers, which causes the reduction of the impact when walking and the increase of the cushioning effect. Applicable to any type of footwear regardless of sex and age.

This invention relates to the field of the shoemaking and themanufacture of footwear and parts thereof, as well as taking care of theintegral health of the human by benefitting the footstep and reduces theimpact when walking.

BACKGROUND

Nowadays, there are different technical solutions that describe shoes orcomponents thereof such as shoe soles, heels that favor the cushion ofthe impact when walking in a aesthetic way, most of people use rubbersoles of transparent materials. The most relevant are described below.

The patent WO200298256 protects a type of sporting shoe that contains acolored liquid or gel in reservoirs that communicate using transparentpipes with the shoe sole. These are external, visible and can extendthroughout the shoe. Its function is to absorb and visualize the shockof impact. On its behalf, the utility model JP05018305U suggests avibration damping material that is in the clear shoe sole, objectivelyin the midsole forming prismatic projections.

The patent JP09182603 suggests a shoe that is fitted with a cushioningin the heel that is composed of two chambers. The first is transparentand is filled with a liquid or gel, is linked with the second availableon the shoe sole and both are filled with gas cells between their walls.The shoe sole has openings that allow the composition of the gel thatcan be seen from the outside. In the case of patent EP0500247 describesa shoe with a sole which presents peripheral edges and an element ofcushioning with joint flexion in the camera, with flexible andtransparent walls, filled with a liquid gel-based composition that istransmitted by the partitions.

The patent JP02191403 protects a shoe sole that absorbs shocks, throughthe inclusion of a soft and elastic body transparent with compressionholes in the heel. These holes consist of circular shapes, ellipticaland polygon elements in the horizontal section and are drilledvertically in a transparent body composed of polyvinyl chloride resinand transparent rubber. Also, the utility model CN201675126OR describesa novel elastic shoe sole that presents a block of cushioning in theheel, which has different colors on both sides of rubber and istransparent.

The technical object of the invention refers to a clear shoe sole, softand flexible polyurethane and a gel-associated shoe template, which arematching dampers ovals that increase the damping when walking. Thisdesign improves the cushioning effect of the footfall, as well as allowsthe removal of the soleplate of the shoe to visualize and feel itstechnical qualities.

DETAILED DESCRIPTION OF THE INVENTION

The shoe sole of the present invention is transparent (1), soft andflexible, made of polyurethane and presents oval-shape shock absorbersof the step (when walking. It is complemented with a soleplate thatcontains gel (1) and the same design of ovals being both matching andengaged, causing an increase of the cushioning effect.

Shoe sole, sole plate and soleplate.

Its technical characteristics as the inner qualities of cushioning canbe felt and observed due to the design they present, in addition toreduce the impact of the footfall to walk (3). The soleplate consists ofa system that allows taking it out of the shoe to appreciate itsqualities.

May be applied to any type of footwear, either as a child, woman, man.Casual, semi-formal, school, sports and sandals what offers you a greatversatility.

During the manufacturing process, the injection of polyurethane shoesole avoiding that the transparent area is contaminated with anothercolor gel is carried out. It is a rather cheap procedure, in which thematerials used represent 10 per cent of its cost. In addition, thecoupling process for the ovals in the shoe sole and soleplate requires aspecial design.

1. Sole plate associated with soleplate that presents special design andmatching characterized because it reduces the impact when walking andincreases the power of cushioning.
 2. Shoe sole associated with asoleplate that presents special design and matching according to theclaim 1, wherein the shoe sole is soft transparent and flexible.
 3. AShoe sole associated with a soleplate that presents special design andmatching according to claim 1, wherein the shoe sole is made ofpolyurethane.
 4. A Shoe sole associated with a sole plate that presentsspecial design and matching according to claim 1, wherein the shoe solepresents cushioning ovals of steps when walking.
 5. A shoe soleassociated with a shoeplate with special design and matching accordingto claim 1; wherein shoeplate contains gel and the same design of thesoleplate ovals.
 6. Soleplate associated with template with specialdesign and matching according to claim 1, wherein technicalcharacteristics and the inner qualities of cushioning can be felt andobserved due to its design and transparency.
 7. A shoe sole associatedwith a shoeplate with special design and matching according to claim 1;wherein shoeplate may be taken out from the shoe to appreciate itstechnical characteristics thereof.
 8. Shoeplate associated with a shoeplate with special design and matching according to claim 1, whereinthey apply to all kinds of footwear regardless of the age and sex.
